1. FRONT AXLE
1.1 DESCRIPTION
The Dana Spicer S84U front axle is of the
‘’Reverse Elliot’’ type manufactured by Dana
Spicer Europe. The front axle consists of a girder
section axle bed or beam with stub axles. Each
stub axle is carried on a taper kingpin, with a plain
phosphor bronze bushing at the top and at the
bottom. The unitized hub bearings used on the
NDS range of axles, are non-serviceable items.
Bearings are pre-adjusted, lubricated and have
seals fitted as part of the manufacturing process.
The bearings are greased for life and there is no
need or facility for re-lubrication. Brakes are
manufactured by KNORR-BREMSE. Steering ball
joints with hardened balls and rubbing pads
incorporate compression springs which
automatically take up any wear.
The tie rod simplifies toe-in adjustment. The
maximum turning angle is set through stop
screws installed on the inner side of the knuckle.
Steering stabilizer (damper) and steering drag link
which are mounted on the front axle are
described in Section 14;
‘’Steering’’ of this
manual.
